DETAILED DESCRIPTION

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. Where possible, like reference numerals have been used to indicate like elements, and repetitive disclosure has been omitted. However, the scope is not limited to the disclosed embodiments, and those skilled in the art may easily suggest other embodiments within the same scope of the idea.

Air conditioners are home appliances that maintain indoor air at a most proper state according to a use and purpose thereof. For example, air conditioners may maintain indoor air in a cool state in summer and a warm state in winter. Further, air conditioners may control a humidity of indoor air and adjust indoor air to a pleasant, clean state. Such an air conditioner, in which a refrigeration cycle is driven, may include, for example, a compressor, a condenser, an expansion device, and an evaporator.

Such an air conditioner may further include a suction device that suctions air within an indoor space, a heat exchanger that exchanges heat with the air suctioned via the suction device, and a discharge part that discharges the air heat-exchanged in the heat exchanger into the indoor space. Also, the air conditioner may include a blowing fan that generates an air flow from the suction device to the discharge part.

When power of the air conditioner is ON and a command for execution of a specific mode is input, the compressor and the blowing fan may be driven to perform a cooling cycle corresponding to the specific mode. The specific mode may include, for example, a cooling mode, a warming mode, and a dehumidification mode.

Typical air conditioners are configured such that a user directly operates an input provided in or on the air conditioner, so as to select a specific mode. Such air conditioners may be provided with a display, on which information (hereinafter referred to as “operation information”) on an operation of the air conditioner may be displayed. When the input is operated, a changed figure of the operation information may be displayed.

In the case of typical air conditioners, as the input is a button type, it may be inconvenient for a user to operate. Also, a window of the display changed whenever a button is pushed may be difficult to operate, and thus, a user may not easily operate the air conditioner. Therefore, many interests are focused on easily implementing the configuration of the input and the display to operate the air conditioner.

FIG. 1 is a schematic perspective view of an air conditioner according to an embodiment, while FIG. 2 is a schematic view illustrating a display of FIG. 1.

Referring to FIG. 1, an air conditioner 10 according to this embodiment may include a suction part 12, a discharge part 15, and a case 11 that forms an appearance thereof. The air conditioner 10 of FIG. 1 may be an indoor device installed in an indoor room to discharge air therein.

The suction part 12 may be formed at a lower side of the case 11. A suction vein 13 to open or close the suction part 12 may be provided at one side of the suction part 12. The suction vein 13 may be rotatably disposed.

The discharge part 15 may be formed at an upper side of the case 11. A discharge vein 16 to open or close the discharge part 15 may be provided at one side of the discharge part 15. The discharge vein 16 may be rotatably disposed.

A front panel 20 may be provided on a front side of the case 11. The front panel 20 may be provided with a display 101 that displays information on an operation of the air conditioner 10. The display 101 may be a, for example, touch screen type display.

Referring to FIG. 2, the display 101 according to this embodiment may include an area (display area) that displays predetermined information, and an area (input area) to input a user's command. In more detail, the display 101 may include a power input interface 180 to select ON/OFF of the air conditioner 10, a mode input interface 170 to select operation modes for the air conditioner 10, and a wheel input interface 150, which may have a wheel shape.

The power input interface 180 may be disposed at a lower side of the display 101. The power input interface 180 may maintain a status displayed on the front panel 20 regardless of an ON/OFF status of the air conditioner 10.

The ON/OFF status of the air conditioner 10 may be selected via the power input interface 180. That is, pushing of the power input interface 180 one time may allow the air conditioner 10 to be changed to the ON status, and again pushing the power input interface 180 one time may allow the air conditioner 10 to be changed to the OFF status. The power input interface 180 may be lit brightly regardless of the ON/OFF status of the air conditioner 10.

The mode input interface 170 may define a portion of the display 101 and may be an input area selectable by a user. A mode display(s) 172, which may display one or more various operation modes of the air conditioner 10, may be included within the mode input interface 170. The mode display(s) 172 may be configured in an icon form including a predetermined shape(s) corresponding to an operation mode(s). Examples of various operation modes may include a cooling mode, a warming mode, an air cleaning mode, a power saving mode, a moisture removing mode, and a wind blowing mode, classified according to operations of the air conditioner.

The mode display(s) 172 may be an input selectable by a user while displaying a specific operation mode. That is, the mode display(s) 172 may be an input interface.

The mode input interface 170 may be a display which is not displayed on the front panel 20 when the air conditioner 10 is OFF, and which is displayed on the front panel 20 when the air conditioner 10 is ON. In more detail, a light source may be provided behind the mode input interface 170, and may be OFF when the air conditioner 10 is OFF and ON when the air conditioner 10 is ON.

An icon corresponding to a present operation mode may be configured so as to be discriminated from other icons. For example, the icon of a current operation mode may be indicated using the color yellow, and the remaining icons may be indicated using the color white, or the icon of the current operation mode may be indicated by a twinkling specific color and the remaining icons may be indicated by a cloudy specific color.

In summary, one operation mode may be selected through the mode input interface 170. That is, when one of one or more mode display(s) 172 is touched, the air conditioner 10 may be operated in an operation mode corresponding to the touched mode display, and the touched mode display 172 may be indicated by a different color or a brighter intensity of illumination so as to be discriminated from the other mode display parts.

The wheel input interface 150 may be an input that intuitively shows a user that the wheel input interface 150 may be operated in a rotation direction of the wheel, in order to input information on operations of the air conditioner 10. The wheel input interface 150 may define a position on the display 101 and may be an input selectable by a user. The wheel input interface 150 may have a circular or elliptical shape, an inside and outside of which may be divided by circumferential lines.

The wheel input interface 150 may include a temperature display 152 that displays information on a current temperature of an air conditioning space (indoor space) or a set temperature of the air conditioner 10, and a wind intensity display 156 that displays an intensity of wind or air flow discharged from the air conditioner 10. The temperature display 152 may be a display area on which a set temperature of the air conditioner 10 or a current temperature of an indoor space may be displayed. The temperature display 152 may be disposed at a center of the wheel input interface 150.

The wind intensity display 156 may include a plurality of circumferential lines 156a that enclose the temperature display 152. The circumferential lines 156a may have a circular or elliptical shape. At least one of the plurality of circumferential lines 156a may be spaced apart from a neighboring circumferential line to enclose the neighboring circumferential line.

For example, the plurality of circumferential lines 156a may include four circumferential lines, as illustrated in FIG. 2. Of course, the number of the plurality of circumferential lines 156a is not limited to four, but may be two, three, or more.

The plurality of circumferential lines 156a may be displayed brighter, for example, from an innermost circumferential line to an outermost circumferential line according to an intensity of the wind discharged from the air conditioner 10. For example, when the intensity of wind is weakest, the wind intensity display 156 may be configured such that the innermost circumferential line 156a is lit brightly, and when the intensity of wind is strongest, the wind intensity display 156 may be configured such that all of the four circumferential lines are lit brightly.

The wind intensity display 156 may function as a display area that displays the intensity of wind and at the same time as an input capable of recognizing a user's manipulation. For example, information on a set temperature value may be input through the display area of the wind intensity display 156.

In summary, the wind intensity display 156 may be configured such that the display area at least partially overlaps the input area. Description related to this function will be provided hereinbelow with reference to the accompanying drawings.

FIG. 3 is a sectional view of a display device according to an embodiment. FIG. 4 is a schematic view of a film according to an embodiment.

Referring to FIG. 3, the air conditioner 10 according to this embodiment may be provided with a display device 100. The display device 100 may be a device disposed behind the front panel 20 to form the display 101.

The display device 100 may include a control box 110 coupled to the front panel 20 behind the front panel 20, and a printed circuit board (PCB) 113 disposed within the control box 110 and provided with a controller 130 (see FIG. 4) that controls the display 101. The PCB 113 may be fixed in the control box 110 by one or more supporter 112.

The display device 100 may include a light emitting device 115 coupled to a front of the PCB 113, a reflector 117 that reflects light emitted by the light emitting device 115, a film 120 coupled to a front of the reflector 117, and a guide 118 that guides the light reflected by the reflector 117 toward the film 120. The light emitting device 115 may be, for example, a light emitting diode (LED).

When information is input through the front panel 20, the film 120 may recognize input of information and deliver the input information to the controller 130. The controller 130 may determine an area to be displayed based on the delivered information, to operate the light emitting device 115, such that information corresponding to the input information may be displayed to the outside through the display 101.

The light emitted from the light emitting device 115 may interact with the reflector 117 and the guide 118 and then move forward. The light may act on at least a portion of areas printed on the film 120, for example, the power input interface 180, the mode input interface 170, and the wheel input interface 150 to brightly light corresponding icons or patterns. As a result, the display 101 may be implemented on the front panel 20.

Referring to FIG. 4, patterns corresponding to the plurality of input interfaces 150, 170, 180 may be printed on the film 120 according to this embodiment. In more detail, the film 120 may include, for example, an indium tin oxide (ITO) film, and a pattern 125 may be provided on one side of the film 121. The film 121 may be a film made of ITO, which is a compound of an indium oxide (In2O3) and a tin oxide (SnO2), and has a sheet resistance of not more than about 103 Ω/sq and a transmittance of not less than about 80%. The ITO film 121 may be configured by attaching an ITO film on a polyester film and then patterning the ITO film through etching.

Patterns corresponding to the input interfaces 150, 170, 180 of the display 101 may be printed on the film 121. In more detail, the film 121 may include a wheel print 122a corresponding to the wheel input interface 150, a mode print 122b corresponding to the mode input interface 170, and a power print 122c corresponding to the power input interface 180. The pattern 125 may be connected to the print 122a, 122b, and 122c, recognize information touched on the respective input interfaces 150, 170, and 180, and transmit the recognized information to an output terminal 126. The pattern 125 may be, for example, configured in a silver ink pattern.

The wheel print 122a may include a plurality of lattice 123 arranged spaced apart by a predetermined distance from one another so as to sense positions touched along circumferences of the wheel pattern. The plurality of lattice 123 may be referred to as “detection lines”, in that they detect touched points. The plurality of lattice 123 may be distributed uniformly along an entire circle (or ellipse) of the wheel.

The plurality of lattice 123 may extend in a radial direction across the plurality of circumferential lines 156a formed in the wind intensity display 156. When a user touches the plurality of lattice 123 in a circumferential direction of the wheel input interface 150, a number of the lattice 123 touched may be detected. By touching the plurality of lattice 150 in the circumferential direction, the user may intuitively perceive that he (or she) rotates the wheel clockwise or counterclockwise.

Herein, the term “touch” may be defined by specific information being recognized in the air conditioner 10 when a touch tool, for example, a user's hand or a touch pen contacts the display 101 or is located within a set distance of the display 101.

For example, case specific information may be recognized by the air conditioner 10, including a case in which a change in pressure or charge (static capacitance) as touched is recognized. Hereinafter, the term “touch” will be described using this concept.

Although it is illustrated that the plurality of lattice 123 extend from an innermost to an outermost circumferential line of the plurality of circumferential lines 156a, the plurality of lattice 123 may further extend beyond the outermost circumferential line 156a by a set length, unlike the illustrated case. In such a case, the outermost circumferential line may be understood to constitute the outer circumferential surface of the wheel input interface 150. However, even when a user touches the display 101 in a rotational direction of the wheel at a point spaced apart by a set distance from the outer circumferential surface of the wheel input interface 150, it may be recognized whether or not the corresponding lattice 123 is touched. In such case in which the wheel input interface 150 is touched in the outer circumferential (rotational) direction, it may be recognized which lattice 123 is touched, and this recognized information may be transmitted to an output terminal 126 through the pattern 125.

The mode input interface 170 corresponding to the mode print 122b and the power input interface 180 corresponding to the power print 122c may be configured such that they recognize whether or not a specific point is touched. Therefore, when the touch of one of the mode display(s) 172 or the power input interface 180 is recognized, whether or not to select the corresponding icons may be determined according to a change in pressure or static capacitance.

The input information transmitted to the output terminal 126 may be delivered to the controller 130 via a driver 135. The driver 135 may be, for example, a driver IC, and may be a device that provides an input signal or input data as an electrical signal.

The driver 135 may be configured to have a plurality of keys according to a color or size to be displayed. The driver 135 and the controller 130 may perform signal transmission according to I2C communication protocol. The I2C communication protocol is a synchronous communication method, and may be understood to be a serial communication protocol.

The controller 130 may operate an operating device 80 based on the signal transmitted from the driver 135, control the operation of the air conditioner 10, and control the light emitting device 115 to display information on the corresponding operation on the display 101. The operating device 80 may include a compressor or a blowing fan.

FIGS. 5A-5B are schematic views illustrating operation of a wheel input interface according to an embodiment. Referring to FIGS. 5A and 5B, a wheel input interface 250 according to this embodiment may include a time display 253 indicating operation time information along a circumferential direction, and a current temperature display 251 positioned at a center of the wheel to display a current temperature.

The time display 253 may display, for example, 24 hours a day along the circumferential direction. The wheel input interface 250 may further include a start time display 259a indicated by a line that extends in one direction from the temperature display 251 to a point on the time display 253, and an end time display 259b indicated by a line that extends in another direction from the temperature display 251 to another point on the time display 253. For convenience of explanation, the start time display 259a may be referred to as a “first line” and the end time display 259b may be referred to as a “second line”.

The start time display 259a may indicate the operation start time of the air conditioner 10, and the end time display 259b may indicate the operation end time of the air conditioner 10. An inner area defined by the start time display 259a and the end time display 259b with respect to an entire inner area may correspond to an operation time of the air conditioner 10 with respect to a 24 hour day. In summary, the enclosed area formed by connecting the start time display 259a, the end time display 259b, and a portion of the circumference of the wheel input interface 150 may define an operation time area 256 indicating the operation time or reservation time of the air conditioner 10.

A color or intensity of illumination of the operation area 256 may be discriminated from the rest of the wheel input interface 250. For example, the operation time area 256 may be formed darker or brighter than other areas.

When a user touches the time display 253 in a clockwise or counterclockwise manner or drag, the operation time or reservation time may be set through the touched position or distance of the lattice 123. In more detail, when a user starts to touch the start time display 259a or the end time display 259b and continues to touch the same in a disposition direction of the time display 253, for example, clockwise or counterclockwise, the start time display 259a or the end time display 259b may rotate. With this process, the operation time area 256 may be expanded or decreased.

An operation mode display 255 that displays an operation mode of the air conditioner 10 may be included within the operation time area 256. For example, the operation modes may include “cooling”, “warming”, “dehumidification”, and “air cleaning”.

A set temperature display 257 may be disposed on any one of the start time display 259a and the end time display 259b. The set temperature display 257 may be provided movable along the start time display 259a or the end time display 259b.

In more detail, when a user moves the set temperature display 257 in an outer direction thereof (away from the current temperature display 251) through a touch, the set temperature may be increased, and when a user moves the set temperature display 257 in an inner direction thereof (toward the current temperature display 251), the set temperature may be decreased.

At this time, recognition of the increase or decrease of the set temperature through a touch may be performed by recognizing a distance corresponding to a length direction of the lattice 123, and a temperature value displayed on the set temperature display 257 may be changed corresponding to the moved distance of the set temperature display 257.

A wind intensity display 258 may be disposed on the other of the start time display 259a and the end time display 259b. The wind intensity display 258 may be provided movable along the start time display 259a or the end time display 259b. The movement mechanism of the wind intensity display 259 may be similar to that of the set temperature display 257.

In more detail, when a user starts to touch the wind intensity display 258 and continues to move the same in the outer direction, the wind intensity may be strengthened, and when the user moves the wind intensity display 258 in the inner direction in the state that the wind intensity display 258 is touched, the wind intensity may be weakened. That is, the wind intensity display 258 may move in the touch direction.

For example, when the wind intensity display 258 is positioned at approximately a center on the start time display 259a or the end time display 259b, the wind intensity may be displayed as “middle” or “medium”, when the wind intensity display 258 is positioned at an outer side on the start time display 259a or the end time display 259b, the wind intensity may be displayed as “strong”, and when the wind intensity display 258 is positioned at an inner side on the start time display 259a or the end time display 259b, the wind intensity may be displayed as “weak”.

In summary, the set temperature display 257 may be disposed movable on one of the lines of the start time display 259a and the end time display 259b, and the wind intensity display 258 may be movably disposed on the other one. In more detail, when a user moves the wind intensity display 258 in the outer direction, the wind intensity may be increased, and when a user moves the wind intensity display 258 in the inner direction, the wind intensity may be decreased. At this time, recognition of the increase or decrease of the wind intensity through a touch may be performed by recognizing a distance corresponding to a length direction of the lattice 123.

Thus, as the set temperature display 257 and the wind intensity display 258 may be provided on the start time display 259a or the end time display 259b to adjust the set temperature or wind intensity along the displays 259a and 259b, a user may input information on the operation of the air conditioner 10, intuitively and easily.

The operation mode displayed on the operation mode display 255 may be changed by touching the inner area of the operation time area 256 or the operation mode display 255. The operation mode display 255 may be disposed within the area defined by the first line and the second line of the wheel input interface 250 and the circumferential surface of the wheel input interface 250.

As described above, first information on the operation of the air conditioner may be displayed on the first line, and second information on the operation of the air conditioner may be displayed on the second line. For example, the first information may be one of set temperature and discharged wind intensity of the air conditioner, and the second information may be the other.

In more detail, a plurality of preset operation modes may be defined in the air conditioner 10, and when the operation time area 256 or the operation mode display 255 is touched, one operation mode displayed on the operation mode display 255 may be changed into another operation mode and then displayed. To change the operation mode, the operation mode display 255 may be directly touched, or an area formed at an outer side of the operation mode display 255 in the inner area of the operation time area 256 may be touched. In this case, the controller 130 may change the content displayed on the operation mode display 255 based on the input information to control the operation of the air conditioner 10 according to the changed operation mode.

In summary, the operation mode display 255 may define the display area displaying information on the operation mode in the display, and the operation time area 256 enclosing the operation mode display 255 may be defined as an input to input information on the operation mode. For example, as illustrated in FIGS. 5A and 5B, while the air conditioner 10 is operated in the cooling mode, “cooling” may be displayed on the operation mode display 255, correspondingly to this mode. When a user touches an inner area of the operation time area 256 or the operation mode display 255, the displayed operation mode may be changed. That is, as illustrated in FIG. 5B, “cooling” may be changed to “heating”. At this time, the sequence of the operation modes to be changed among the plurality of operation modes may be set in advance.

To change the display of the operation mode, the touching of the inner area of the operation time area 256 or the operation mode display 255 may be performed by touching the operation time area 256 once or maintaining the touched state during a set time or more. In a case in which the operation time area 256 is touched once, the display of the operation mode may be changed whenever touched. On the other hand, if the touched state of the operation time area 256 is maintained during a first set time or more, the display of the operation mode may be changed in a preset sequence. The time interval where the display of the operation mode is changed may be a second set time.

For example, the first set time may be about two seconds, and the second set time may be about one second. That is, when the operation time area 256 is touched for about two seconds or more, the change of the display of the operation mode may start. For example, the display may be changed in a sequence of cooling→warming→dehumidification→air cleaning. The time interval during which one operation mode may be changed to another operation mode, may be set to about one second.

According to the above configuration, as the operation mode display 255 may be disposed within the operation time area 256, the display of the operation mode may be easy and a user may easily confirm the operation mode. Also, as the operation mode display may be provided on a position within the wheel input interface and the operation mode may be changed by a touch and then viewed by a user, the display and change of the operation mode within a limited area may be made easy. Further, as the operation mode may be changed not only by touching the small operation mode display 255, but also by touching the operation time area 256, which is larger than the operation mode display 255, the display device may be convenient for a user to operate.

FIGS. 6A-6D are schematic views illustrating a display according to another embodiment. Referring to FIG. 6, a display 301 according to this embodiment may include a wheel input interface 350, which may have a circular or elliptical shape, and a mode input interface 370 provided on an outer side of the wheel input interface 350 to input the operation mode of the air conditioner 10.

One or more mode display(s) 372 corresponding to one or more operation modes of the air conditioner 10 may be included within the mode input interface 370. The one or more mode display(s) 372 may form predetermined areas for input. As illustrated in FIG. 6A, the operation modes displayed may include, for example, “cooling”, “dehumidification”, “warming”, and “air cleaning”.

The wheel input interface 350 may include a current temperature display 351 provided on an inner center of the wheel input interface 350 to display a current temperature value, a wind intensity display 356 disposed to enclose the current temperature display 351 to display a degree of wind intensity, and a set temperature display 357 disposed at a portion of the wind intensity display 356 to display a set temperature value of the air conditioner.

The wind intensity display 356 may include a plurality of circumferential lines 356a having a closed circular or elliptical shape. Description on the plurality of circumferential lines 356a is similar that of the previous embodiment, and thus, repetitive disclosure has been omitted.

The mode display(s) 372 may be configured to be touch-input. That is, the mode display(s) 372 may be configured to display operation mode information and at the same time to enable a user to input the operation mode. That is, the mode display(s) 372 may be defined as an input area.

When one of operation modes included in the mode display(s) 372 is selected, the configuration of the wheel input interface 350 may be determined corresponding to the selected one mode. For example, the color of one of the plurality of circumferential lines 356a may be changed according to the selected operation mode. That is, the configuration of the circumferential line 356a corresponding to the respective operation mode may be changed.

For example, FIGS. 6A to 6D illustrate the configuration of the display 301 as selected in a sequence of cooling, dehumidification, warming, and air cleaning. As illustrated in the drawings, the color or texture of an outermost circumferential line of the plurality of circumferential lines 356a may be different according to the selected operation mode. That is, the configuration of the wheel input interface 350 may be displayed differently according to the selection of the input area (mode display(s)).

In summary, mode display(s) 372 capable of selecting the operation mode may be provided at an outer side of the wheel input interface 350. When one of the mode display(s) 372 is selected, the controller 130 may perform a control such that the configuration of the wheel input interface 350 is changed according to the selected mode display 372.

According to the above configuration, as a user may perform a touch and then confirm a control item of the air conditioner 10 through the display 301, product reliability may be enhanced.

FIG. 7 is a schematic view of an air conditioner according to another embodiment, while FIG. 8 is a schematic view of a display of the embodiment of FIG. 7. Referring to FIG. 7, an air conditioner 410 according to this embodiment may include a front panel 430, and a discharge part 415a, 415b disposed at both sides of the front panel 430 to discharge air. A discharge grille to prevent foreign particles from being introduced or discharged may be provided on or at each of the discharge parts 415a and 415b. The front panel 430 may be provided with a display 401. The discharge parts 415a, 415b may include a first discharge part 415a disposed at one side of the front panel 430, and a second discharge part 415b disposed at the other side of the front panel 430.
